I cut a plywood circle the same diam as my front tire. Then I could test the different positions without the bike and decide which one to use. I have the HF Condor knockoff.

 

I have stock 2011 ultra. 3rd hole.

 

Condor chock pin setting for the cradle is all the way to the back on mine. With my 14 sgs I still need a little push to get it out. Wife gives me a shove taking hold of the engine guard from in front of the bike. I’m just getting old and feeble I guess.

 

Went and looked this morning, was at the shop anyhow.
I run the same size tire on an 08 UC.
Third hole is the best for me
I made some trial ad error attempts when I bought the chock just didn't remember right off.
